Abstract
A centrifuge includes a rotator comprising a receiving unit receiving materials and guiding the materials to move upward by centrifugal force to an upper portion of the receiving unit, and a rotator cover covering the upper portion of the receiving unit. The centrifuge also includes a container that is coupled to the rotator cover to be connected to the receiving unit and that receives the materials moved upward along the receiving unit. The centrifuge and a centrifuging method as disclosed herein are used for separating a fluid to which a large centrifugal force is applied and a fluid to which a smaller centrifugal force is applied by adjusting the rotation speed using the principle that centrifugal force during rotation varies according to specific components of a fluid. Thus, using the centrifuge and the centrifugal method, materials can be centrifuged and layers of the materials can be classified and collected accurately and easily.
